AUTOMOBILE-WHEEL.

Specification of Letters Patent.

Patented Sept. 12, 1911.

To all whom it may concern:

Be it known that I, Anonnw SALTZER, citizenjof the United States,residing at Sawtelle; in the county of Los Angeles and State ofCalifornia, have invented certain new" and useful improvements inAutomobile-Wheels, of which the following is a specification.

My invention relates to improvements in automobile wheels.

The objects of my invention are to provide a wheel for automobiles thatis puncture proof, and dust proof; and to so construct and arrange theparts that when the machine is in motion the rebound of the body whenthe wheels are passing over an obstruction or into a depression, isobviated to a great extent.

Further it is aimed to obviate the necessity of using pneumatic tires ortubes on the outer periphery of the wheel, and. to make a cheap,durable, and eflicient wheel for the purpose stated.

These objects I accomplish by the con siruction shown in theaccompanying drawings in which,

Figure .1 is a vertical sectional view of my improved vehicle wheel.Fig. 2 is a front sectional view taken on line 2 2 of Fig. 1 showingfully the construction and arrangement of the 18tliI1eL',llI1l S, Fig. 3is an inner vertical view of the wheel casing, showing the constructionof the anti-friction side bearings, Fig. 4.- is a side elevation ofsame, Fig. 5 is 1 side elevation of the wheel,

' Fig. 6 is an enlarged sectional view taken on line 66 of Fig; 2showing the construction of the retainer links, and antifriction sidebearings secured upon the inside of the casings. Fig. 7 is a transverseview of same showing the retainer links secured in position, the sideplate being broken away to show the antilriction bearings secured to theouter casing. Fig. 8 is an enlarged sectional view of my improved wheelto show more fully the construction and arrangementof the partsconstituting the invention.

Similar letters and figures of reference indicate the several partsthroughout the several views.

In the accom 'ianying drawings A represents the center or hub of thewheel, which is composed of two circular disks 01' plates 1, 1, securedupon each side of the center band is secured the cleuch-ring 5 inwhicliis placed, and secured the flanges of the pneumatic tube 6 which tubemay be rubber or leather or any flexible material.

The inner tube 7 is composed of rubber 'and is similar to the innertubes used Within the casing of a pneumatic tire being inflated in theusual manner.

8, 8 are circular disks forming the wheel proper, the said disks beingprovided upon their outer peripheries with outwardly projecting flanges9, 9. The disks 8,8 are held a given distance apart by being rivetedtogether to .the metal rimil by means of rivets 1O passing'through'theflanges 9, 9, rim 11, and clench rim 12. The inner edges 13, 13, ofdisks 8, 8, are bowed outwardly and form a seat in which engages theouter periphery of the pneumatic tube 6.

The tire 14 maybe composed of solid rub ber, leather, or any suitableflexible material. 4,

15 represents links formed with slots 34, the links being pivotedbetween the disks 8, 8 in the space provided by the two disks. The links15 are of the form shown in Figs, 6 and 7, and are pivoted in pairs uponpins 16 which pass through the same, the ends of the pins or hearingsbeing riveted through the plates 8. 8. The objects of the links will bemore fully described hereinafter.

.17 represents the inner sheet metal casing which covers one side of thepneumatic tube. The said casing is pressed concave in line with thepneumatic tube, the inner portion and outer portion being fiat. Theinnor and outer casings 17 and 18 are similarly formed except the casing18 is made in two parts 19 and 20. The part 20 is provided with anoutwardly projecting flange 21 formed around the opening of the disk andthreaded upon the outside and the pot tion 19 is formed with aninwardlyprojecting fiange 22 threaded upon the inside. The object ofhaving the center part 19 detachable is for the purpose of access to thepneumatic tube when necessary. The outer edges 23 and 24 of the casings18 and 17, respectively are bent inwardly forming a space or hollowportion 26 upon both sides of the wheel. The spaces are formed toreceive a series of ball-cups 27 'one line above the line of retainerlinks andone line below the same. The said cups fit in recesses 28pressed into the casings 17 and 18. The balls 29 are held within thecups by the curved studs or bolts 30.

31 indicates stay bolts which are twelve in number and extend throughboth casings.

A sleeve 32 is placed over each stay bolt and has its ends bearingagainst the inner face of the casings 17 and 18. The said bolts andsleeves pass through the slot holes 34 in the outer ends of the retainerlinks 15 and openings 35 in the wheel plates 8 and 8. The balls 29 bearagainst the outer face of the wheel plates 8, 8. The objects of the ballbearings is to allow a sliding movement between the parts of the wheel.The object of the links is to prevent the outer portion of the wheelfrom turning on the pneumatic tube 6 when the brake is applied. The hub36 of the wheel is secured to the center block and wheel plate by bolts87 passing through the hub-flanges 38 casings 17 and 18 and center block2 clamping all the parts firmly together. This is fully illustrated inFigs. 1 and 8.

It will bereadily seen by those skilled in the art, that all danger frompuncture is obviated as the pneumatic tire does not come in contact withthe ground, and that the easings covering the pneumatic tire makes itdust proof as well. The pneumatic tire forms a spring between the tireportion of the wheel and the axle of the vehicle, and in conjunctionwith the body springs prevents nearly all rebound between the trucks andwheels.

The retainer links 15 which are pivoted together attheir inner ends inpairs prevent the tire or outer rim of the wheel from rotating aroundthe hub of the wheel and they also obviate all vibrating or backlashwhen rotating. the vehicle. They cause the wheel to rotate in a mannersimilar to a solid wheel and still allow' all necessary springvertically upon the pneumatic tube.

The pneumatic tube is held upon the hub from rotating with respect tothe same by the clench-rim 5.

What is claimed is:

A wheel including a hub, a pneumatic tube secured to the hub, a pair ofspaced disks seating on the pneumatic tube, a tire secured to theperipheries of the disks, slotted links having their adjacent ends inengagement, bolts passing throu h the disks and said adj acent ends ofthe links, an outer casing inclosing the pneumatic tube, said outercasing comprising a pair of oppositely disposed members arranged inspaced relation to the disks, said members pressed outwardly to receiveball bearings alternately above and below the said links, and stay boltssecured to said outer members and passing through the slots in thelinks.

In testimony whereof I aifix my signature, in presence of two witnesses.

ANDREW SALTZER.
